Question

what will be the value of refractive index of alcohol with respect to carbon disulphide the refractive index of alcohol with respect to air is 1.36 and the query effective index of carbon disulphide with respect to air is 1.63

Answer 1

the refractive index of alcohol with respect to carbon disulphide is 0.834

Answer 2

given that
refractive index of alcohol with respect to air(μ₁ₐ)=1.36.............(1)
&
refractive index of CS₂ with respect to air(μ₂ₐ)=1.63..............(2)
operating equations (1)/(2)
μ₁ₐ/μ₂ₐ=1.36/1.63
⇒(μ₁/μₐ) / (μ₂/μₐ)=1.36/1.63
⇒μ₁/μ₂=1.36/1.63
⇒μ₁₂≈ 0.83
.·. the value of refractive index of alcohol with respect to CS₂ is 0.83(appx.)
